Hadoop was inspired by Google's MapReduce, GoogleFS and BigTable publications. Thanks to the MapReduce framework, it can handle vast amounts of data. Rather than moving the data to a network to do the processing, MapReduce allows the processing software to move directly to the data. It ...
That changed in Hadoop 2.x, which became generally available in 2013 when version 2.2.0 was released. It introduced YARN, which took over the cluster resource management and job scheduling functions from MapReduce. YARN ended the strict reliance on MapReduce and opened up Hadoop to other proces...
Hadoop got introduced in 2002 with Apache Nutch, an open-source web search engine, which was part of the Lucene project. Now that we understood ‘What is Hadoop?’ and got a bit of the history behind it, next up in this tutorial, we will be looking at how Hadoop actually solves the ...
YARN was introduced to make the most out of HDFS, and job scheduling is also handled by YARN. Now that YARN has been introduced, the architecture of Hadoop 2.x provides a data processing platform that is not only limited to MapReduce. It lets Hadoop process other-purpose-built data process...
Originally it was developed by Salesforce.com engineers for internal use and was open sourced. In 2013 it became an Apache incubator project.ArchitectureWe have covered HBase in more detail in this article. Just a quick recap: HBase architecture is based on three key components: HBase Master...
Hadoop, which was built based on the Google proposed algorithm MpaReduce, was first introduced by Doug Cutting and his group in 2005. Then it became an Apache project in 2008 and its improved second version was released in 2012. Hadoop has dominated the Big-Data framework area that it is ...
The MapReduce programming model, in which the data nodes perform both the data storing and the computation, was introduced for big-data processing. Thus, w... JY Cho,HW Jin,L Min,... - 《Parallel Computing》 被引量: 5发表: 2014年 Dynamic File Placing Control for Improving the I/O Pe...
Introduction to Apache Hadoop YARN Hadoop YARN was introduced in Hadoop 2.0 as a major upgrade to its predecessor, the Hadoop MapReduce framework. While MapReduce was primarily focused on batch processing of data, YARN provides a more general-purpose framework that supports a variety of processing...
• By 2007, Hadoop was being used by many other companies besides Yahoo!, such as Facebook, and the New York Times.• 2006 年,他们离开了Nutch,形成了一个独立的Lucene 子项目,称为Hadoop。大约在同一时间,Doug Cutting 加入了 Yahoo!,Yahoo! 提供了一个专门的团队和资源来将 Hadoop 变成一个在...
